Referring now in detail to the drawing, 10 designates a tabulating card punching machine embodying the invention. The same comprises an outer casing 11 having a bottom or base portion 12 and a cover portion 13. The base portion 12 has a bottom wall 14, a front wall 15, a rear wall 16 and side walls 17. The cover portion 13 has a top wall 18, a rear wall 19, side walls 20 and a frontl wall 21. Extending downwardly from the top wall 18 is an inclined wall 22 from'whichextends a curved wall 23 extending to the front wall 21. The walls 20 and 23 are formed with a window opening 24. Behind the window opening 24 is suitably mounted a bezel having an upwardly and rearwardly inclined wall 26 from which extends a downwardly and forwardly curved wall 27. The wall 27 is formed with 12 equally inclined slots 28 disposed in vertical parallel equally spaced planes.

Disposed within the casing 11 is a frame 30. The frame 30 comprises a pair of parallel side plates or walls 31 and 32 having feet 33 supported on suitable legs 34 formed on the bottom wall 14 of the casing. Said side plates are interconnected adjacent the front ends thereof by a pair of parallel spaced horizontal, vertically aligned tie rods 35 and 36. Said side plates 31, 32 are also interconnected by a vertical plate 37 disposed about halfway from front 32 is a transverse horizontal shaft 43 disposed at a level between the tie rods 35 and 36 and somewhat rearwardly of said tie rods.

Interconnecting said side plates 31 and 32, is a trans verse plate 45 disposed substantially at the level of the lower tie rod 35 and between said tie rod and the plate 37. Plate 45 is formed adjacent its front end with equally spaced openings 46 for the purpose hereinafter appearing. The vertical plate 37 is formed with a plurality of vertical equally spaced through slots 37a, communicating with slots 38. The slots 37a are located substantially midheight of the plates 37, and extend somewhat above and below the level of the shaft 42.

Also supported by the side plates 31 and 32 is a horizontal transverse shaft 48 located rearwardly of, and somewhat below the inclined wall 26 of the bezel 25. Said inclined wall 26 of the bezel is formed with a plurality of cutouts or windows 26a for the purpose hereinafter appearing.

Attached to and between the side plates 31 and 32 adjacent to the rear ends thereof, is a bracket 50. Bracket 50 has a rear vertical wall 51 (see FIG. 9). Wall 51 is formed with a central, vertical cutout 52. Extending forwardly from the back wall 51 are a pair of parallel side walls '54 disposed on opposite sides of the cutout 52. Walls 54 are formed with upper and lower vertically aligned slots 55. Fixed to the rear wall 51 and extending forwardly therefrom, are a pair .of parallel upper guide rods 56 and a pair of lower parallel guide rods 57 aligned with the upper guide rods. The guide rods 56 and 57 are located at the outer sides of the parallel walls 54.

Fixed to the front ends of the guide rods 56 and 57 is a vertical plate 60 formed with a rectangular cutout or opening 61 in its upper end. A plate 60 is disposed between the plate 37 and the bracket 50 (see FIG. 9). Attached to the plate '60 by four corner tie rods 62 is a vertical plate 63 disposed forwardly of the plate 60. Plate 63 extends to the height of the upper end of plate 37 but only up halfway down said plate. The upper ends of the plates 37 and '63 are interconnected by top horizontal plate 64. The bottom ends of the plates 60 and 37 are interconnected by a horizontal plate 65. The

- plate 63 is formed at its rear surface with a plurality to rear of the casing. The plate 37 is formed at the rear surface thereof with a plurality of vertical equally spaced longitudinal slots 38. Although 18 slots are shown in FIG. 3, in the embodiment of the invention herein, only 12 of the slots are used. This is so because the illustrated machine is for punching in 12 columns of a tabulating card. It is understood, however, that the machine may be modified for either 6, 12 or 18 punch columns. Be-

tween the slots 38 are walls 39, and attached to the front of closely spaced vertical through slots 67 aligned with the cutout 61. The centers between the slots 67 are spaced similarly to the centers between columns on a tabulating card.

Extending forwardly from the rear wall 51 of bracket 50 is an arm 70. Journaled in said arm 70 and in the side plate 32 is a horizontal shaft 71. Extending from said wall 51 is another arm 72. Journaled in said arm 72 and passing through a cutout 73 in the side plate 32 is a horizontal shaft 74 disposed rearwardly of and somewhat below shaft 71.

Interconnecting the sideplates 31 and 32 is a transverse horizontal bar 75 disposed rearwardly and up above the shaft 42 and below and forwardly of the shaft 48. The bar 75 may be of square cross-section, with a pair of surfaces thereof inclined to the horizontal and to the vertical, as shown in FIGS. 4 and 5 of the drawing.

Rotatably mounted on shaft 42 are a plurality of hubs 76 and mounted on and fixed to each hub is a setting wheel 77. In the drawing, 12 such wheels are shown, although as stated above, the machine could be made with either 6, 12 or 18 of such wheels, depending upon the number of columns it is desired to punch at once on the tabulating card. Each Wheel 77 has a central portion 78 mounted on one of the hubs 76. Each wheel 77 is also formed with an annular rim portion 79. The rim comprises a portion having a portion formed with V- shaped teeth 80 and V-shaped notches 80a between said teeth, and a gear tooth portion 81 extending from one end of the portion which has the V-shaped tooth 80, and extending through an angle of somewhat less than Adjacent the end of the gear tooth portion 81, is a radial portion 82 which extends outwardly in the plane of the wheel, and formed at its outer end with an offset flange 83. Flange 83 is formed with a longitudinal slot 84. Fixed to one side of each wheel 77 adjacent the extension 82 is a headed pin 85. Slidably mounted through each slot 84 is a radial setting lever arm or bar 86 formed with a radial slot 87 through which the pin 85 passes. The upper end of arm 86 is slotted and hence bifurcated as at 88, and frictionally mounted on the upper end of said arm is a setting finger grip button 89. Extending from the lower end of each arm 86 is a finger 90 connected by a coil tension spring 91 to the flange 83. The arm or lever 86 may be pushed radially downwardly, the movement of each arm being limited by the length of slot 87. At the rear edge of each arm 86' is a notch 91 forming a shoulder to engage the rear end of slot 84 of flange 83 to retain the depressed lever or arm 86 and its button 89 in depressed condition.

It will be understood that each arm 86 passes through one of the slots 28 in the bezel 25. Arms 86 pass through the Window opening 24 in wall 23 of the casing. It will be further understood that the wheels 77 may be selectively rotated by engaging the buttons 89 of the respective wheel and pulling the buttons downwardly and forwardly.

Each wheel 77 has an extension 92 disposed radially inwardly of the outward extension 82. At the rear end of each extension 92 is a finger 93 adapted to contact the transverse stop bar 75 to limit rotation of the wheel 77 in a clockwise direction, looking at FIG. 5 of the drawing,

back to initial position. On each extension '92 is a pin 96, and pivoted thereto is a pawl 97 having an upwardly and rearwardly extending arm 98 connected by coil tension spring 99 to the flange 83. Thus the springs 99 bias the pawls 97 in a clockwise direction, looking at FIG. 5 of the drawing. Each pawl 97 includes an arm 100 extending downwardly and forwardly and formed with an upwardly extending finger 101. It will be noted that when a button 89 is depressed, spring 81 is tensioned and the lower end of the setting lever or arm 86 rotates the pawl 97 in a clockwise direction, thereby tensioning also the spring 99 and moving the offset finger 101 radially outwardly towards the outer rim edge of the wheel 77. The arm 86 will remain in such a position if the arm is also tilted rearwardly to engage notch 91 with the rear edge of the slot 86. Each button may be released by pushing it forwardly slightly to disengage the notch 91 from the flange 83, permitting spring 99' to pull arm 86 radially outwardly and thereby permitting the spring 99 to swing pawl 97 in a counterclockwise direction.

Fixed to the tie rods 35, adjacent to and to the right of each wheel 77, is a member 105 which may be made in the form of a thin plate. Member 105 has a vertical portion 106 formed with openings, through which the tie rods and 36 pass. The tie rods 35 and 36 may be formed with annular grooves 35a and 36a to receive 0- clamps 35b and 36b contacting members 105. On said shafts 35 and 36 are spacer sleeves 35c and 360, interposed between members 105 and the O-clamps 35b and 36b, to retain members 105 in spaced, parallel relation adjacent to wheels 77.

Each member 105 has at the upper end thereof, an upwardly and rearwardly curved arm 110 formed at its inner surface with 13 notches 111, with stop fingers 112 between the notches. The notched portion of the arm 110 is located within the angular extension of the slots 28. The first, middle and last portions 28a of the bezel between slots 28 may be divided into 13 equi-angular parts numbered successively from top to bottom, B, 12, 11, 0, l, 2, 3, 4, 5, 6, 7, 8, 9 as shown in FIG. 1 of the drawing. Position B is the initial position. The intermediate portions 28a may be marked off into 13 equi-angular portions without numbering, also as illustrated in FIG. 1.

When wheel 77 has been rotated in a clockwise direction, looking at FIG. 5, to a point where the finger 93 contacts the shaft 75, the setting button 89 will be at the upper end of slot 28 opposite a space marked B. When the setting lever 86 is disengaged from the flange 83 and is in its radial outermost position, the finger 101 of the pawl 97 associated therewith is disengaged from any of the notches 111 of the member associated therewith. The setting button 89 may be pulled downwardly and forwardly by the operator to any desired angular position, opposite any number from 12 to 9.

Means is provided to releasably retain the setting wheels 77 in any positions to which they are moved. To this end there is pivoted to shaft 43, 12 bell cranks 120, each having a rearwardly extending arm 121 provided with a pin 122 carrying a roller adapted to engage in a V-shape notch 80a of wheel 77. Each bell crank furthermore comprises a downwardly extending arm 123 connected to a horizontal coil tension spring 124 which engages one of the openings 46 of the transverse bar 45. Thus, the springs 124 tend to retain the pins 122 in engagement with the notches 80a between the V-shaped teeth 80 of the wheel 77. As the wheel is turned the pins 122 click into the notches so as to hold the wheels in one of 13 positions.

Supported on member 126, at the ends of plate 37 is a horizontal shaft 127 on which are rotatably mounted pinions 128 meshing with the gear teeth 81 of the respective wheels 77, for the purpose hereinafter appearing.

Mounted on shaft 48 are pinions 130. Attached to each pinion 130 is an indicator wheel 131 marked on the outside of its periphery with the following, in succession: B, 12, 11, O, 1, 2, 3, 4, 5, 6, 7, 8, 9. The arrangement is such that for each wheel 77., the location of the button will be indicated on the indicator wheel 131 as seen through a window 26a. There are 12 windows 26a one for each button. If a button is opposite 6 as indicated on portions 28a of the bezel, then 6 will show through the window associated with said button. In this manner, the operator by glancing at the window will have a quick visual indication of the location of the setting buttons, to make sure that the buttons have been correctly set.

Means is provided for simultaneously rotating all of the bell cranks 120 in a clockwise direction to release all the settings of wheel 77 so that they can be returned to their initial positions indicated by the letter B. To this end there is mounted on the shaft 43 a cross-bail 135 having radial arms 136 interconnected by a longitudinal transverse portion 137. The portion 137 is located between arms 121 and 123 of the bell cranks, as shown in FIG. 5. Attached to the portion of shaft 43 which projects to the right of the side plate 32 is an arm 137a, formed at its outer end with an oifset pin 138 carrying a rack 138a. When arm 137a is moved, in a manner to be explained hereinafter, in a clockwise direction, the bail 135 will engage all of the clamps 120, rotating said clamps in a clockwise direction, permitting restoration of the wheel 77, in the manner hereinafter explained, to the initial position.

Means is provided to return the wheels 77 to their initial positions when released. To this end there is mounted on shaft 43, a bail 140 comprising arms 141 interconnected by a transverse portion 142. One end of the cross portion 142 is connected by coil tension spring 143 to a pin 144 fixed to the side plate 32, normally retaining the bail in its downmost position, as shown in FIG. 4 of the drawing. When any button 89 is pulled down with the button radially extended, the finger 101 of the pawl 97 will lie in the path of the bail portion 142. Fixed to the right end of the shaft 42 which extends beyond the side plate 32 is an arm 145 provided at its outer end with a square pin 146. After the buttons have been set, movement of the arm 45 in a clockwise direction, in a manner to be explained hereinafter, will cause the bail 140 to rotate in a clockwise direction, engaging the pawls 97 to return the wheel 77 to initial position. However, if it is desired to inhibit restoration of any for retaining the buttons in engaged condition.

7 selected wheel or wheels 77, the operator need only push the selector buttons 89 radially inwardly and then tilt them rearwardly to engage the notches 91 with the flanges 83 Such action of the buttons will rotate the pawls 97 associated therewith radially outwardly into engagement with one or another of the notches 111, depending upon the angular position or the setting of the button. Thus, not only will the wheel so adjusted be retained in said position, but the finger 101 of the pawl 97 will have moved radially outwardly of the path of the bail so that the next time the am is rotated in a clockwise direction, the Wheels which have been so preset will not be restored by the bail.

Means is provided for accomplishing the release of the clicker bell cranks 120 and for restoring the wheels 77. To this end, there is mounted on the portion of the shaft 71 which projects beyond the side plate 32, an operating lever 150. The operating lever comprises a sleeve 151 received in said shaft and from which extends an arm 152 provided with a crank handle 153 at its outer end. Normally, the operating lever extends upwardly and is located at the outside of the casing, the sleeve 151 passing through a suitable opening in the casing. Fixed to the sleeve 151 is a bell crank 155 having an upwardly and rearwardly inclined arm 156 and a forwardly and upwardly inclined arm 157. Pivoted to a pivot pin 158 on arm 156 is a link 159 which is inclined forwardly and upwardly and is formed at its outer end with a longitudinal slot 160.

: On side plate 32, forwardly of shaft 71, is a short shaft 161 projecting through side plate 32. Provided on said shaft 161 is an arm 162 inclined normally rearwardly and upwardly (see FIG. 4). Adjacent the outer end or arm 162 is a pin 163 passing through slot in link 159 and normally located at the forward end of said slot. The outer end of arm 162 is connected by a coil tension spring 164 to a fixed lug 165 located on side plate 32 above and rearwardly of shaft 71. The spring 164 biases the arm 162 in a clockwise direction, looking at FIG. 4 of the drawing. Pivoted to the shaft or stud 161 is a bell crank 166 comprising an arm 167 extending upwardly and normally overlying arm 162. Bell crank 166 furthermore comprises a forwardly extending arm 166a having an upwardly and forwardly inclined cammed front edge 168. The lower end of edge 168 normally contacts the roller 138a on the pin 138 of the arm 137 which controls the clicker release bail. Pivoted to the forward end of arm 166a, as at 169 is a link 170. Link 170 is formed with an intermediate longitudinal slot 171. Fixed to the side plate 32 is a headed pin 172 passing through slot 171. It will be noted that link 170 is normally inclined upwardly and rearwardly.

Pivoted to the arm 162 below the pin 163, as at 173, is a pawl 174 inclined forwardly and formed at its forward end with a downwardly extending hook 175 having an inner rear straight edge 176 normally inclined downwardly and somewhat forwardly. At the upper end of link 170 is a pin 177a contacting the under edge 174a of the pawl 174 to retain said pawl in an upwardly and forwardly inclined position. The pawl 174 is normally biased downwardly or in a counterclockwise direction, looking at FIG. 4, by a coil tension spring 177 which interconnects an intermediate portion of the-pawl with a portion of the am 162 disposed below pivot pin 173 of the pawl to said arm.

Pivoted to the side plate 32 on a stud shaft 180 located above shaft 161 and rearwardly of arm 162 is a bell crank 181 having an upwardly and rearwardly inclined arm 182 and a forwardly and upwardly inclined arm 183. At the forward under edge of the arm 183 is a notch 184. The bell crank 181 is biased in a counterclockwise direction (FIG. 4) by, means of a coil tension spring 185 which connects the bell crank to a fixed post or pin 186 on side plate 32. The lower edge of arm 183 normally contacts an offset finger 167a at the upper arm 167 and 8. is held against said finger by said spring 185. On arm 162 and below the bell crank 181 is a pin 188 normally spaced from arm .167 but adapted to engage said arm when arm 162 is swung forwardly in a manner hereinafter appearing. On arm 162 is a rearward extension 189. Adjustably mounted on said extension 189, by means of a headed bolt 190 passing through a slot 191 is a plate 192 having an offset finger 193 at its outer end normally contacting the upper end of arm 182 of the bell crank 181. Pivoted to an upwardly extending ear 200 of link 159 as by pivot pin 201, is a bell crank pawl 202 having an arm 203 projecting forwardly into engagement with the pin 163 on the arm 162. The bell crank 202 has an upwardly extending arm 204 connected by coil tension spring 205 to an upwardly extending finger 206 at the upper end of arm 162. Spring 20'5 tends to rotate bell crank 202 in counterclockwise direction, looking at FIG. 4 of the drawing. An offset stop finger 207 on the arm 203 contacts the upper edge of link 159 to retain the forward end of arm 203 in an abutmentwith pin 163. The bell crank 202 further comprises a rearwardly and downwardly curved arm 209 for the purpose hereinafter appearing.

Pivoted to the side plate 32 as on pivot 210, rearwardly of the transverse stop bar 75, and somewhat thereabove is a lever 211. Lever 211 comprises a forwardly and upwardly extending arm 212 projecting through a suitable opening in the casing and having its forward tip 213 exposed so that the operator can swing the lever up or down. Said lever 211 further comprises a downwardly and rearwardly extending arm 214 having an olfset finger 215 overlying arm 209 of the lever 202. Northally the finger 215 is out of contact with pawl 202. How ever, by pushing the finger 213 upwardly, finger 215 will press down on the arm 209 of pawl 202 against the tension of spring 205, to move arm 203 out of the path of pin 163. With the lever 211 in normal position out of contact with pawl 202, when the handle 153 is pulled down by the operator, the link 159 will be moved upwardly and forwardly to cause arm 162 to rotate in a counterclockwise direction. This is done after the setting buttons have been moved to selected positions.

Means is provided to prevent retraction of the operating lever 150 once it has started to be pulled down. To this end, arm 157 of plate 155 is formed with'serrated teeth 157a. O11 side plate 32 of the frame is a pin 220. Pivoted to said pin 220 is a pawl 221 having a rearwardly extending arm 222 connected by a coil tension spring 223 to a fixed pin 224 on the side plate 32. The pawl 221 has a rearwardly projected pointed arm 225 adapted to be engage by the teeth 157a to prevent retraction of the operating lever until all of the said teeth move past the pawl, thereby insuring complete operation of the operating handle before it is retracted or swung upwardly.

The operating handle has a total movement of 90. As the handle starts to be swung down, arm 162 is swung in a counterclockwise direction due to engagement of arm 203 of pawl 202 with the pin 163. As arm 162 starts to rotate, the hooked pawl 174 is moved forwardly. When the pin 188 on the arm 162 engages arm 167, the bell crank 166 is rotated in a counterclockwise direction, thereby causing the cammed edge 168 on the arm 166a engaging roller 138a on the pin 138, to rotate arm 137 in a clockwise direction, thereby causing the bail 135 to swing in a clockwise direction, looking at FlG. 5 of the drawing, to release the clicker levers 120 from engagement with the wheels 77. The swinging move ment of the bell crank 166 in a counterclockwise ditreotion will permit lowering of the pawl 174 as the latter is moved forwardly. Continued movement of the operating lever will cause thehook 175 to engage the square stud 146 on arm 145. The edge 176 of the hook 175 will engage one surface of said square stud. As the bell crank 166 is swung in a counterclockwise direction, furthermore, the finger 167a on the arm 167 of said bell crank will move outwardly of arm 183 of the locking pawl or bell crank 181, permitting the spring 185 to rotate said locking pawl in a counterclockwise direction, to engage the finger 167a within the notch 184. At this time the operating lever is at the bottom of its stroke.

Means is provided for swinging the operating lever upwardly to its normal position after it has been pulled down through an angle of 90 and released. To this end there is mounted on shaft 71 a torsion spring 230 (FIG. 3). Having one end 231 engaging a radial pin 232 on said shaft, the other end of said torsion spring may be fixed to any suitable post at the inside of side plate 32. As the operating lever is pulled down, shaft 71 is rotated, thereby tensioning the torsion spring 230 to raise the operating lever when the latter is released.

After the operating lever has been pulled down and released, it starts moving upwardly, thereby swinging arm 162 in a clockwise direction thereby causing pawl 174 to rotate arm 145 in a clockwise direction, thereby causing bail 140 to swing in a clockwise direction, to thereby restore the wheels 77 back to initial position, due to engagement of the bail with the pawls 97. Of course, if any setting button 89 has been pushed in and engaged with the flange 83, the wheels that carry said setting buttons will not be restored. During this retracting movement of the operating lever :and the restoring of the uninhibited wheels 77, bell crank 166 remains locked by the pawl 181. Near the upper end of the upward stroke of the operating lever, member 170 will lift the pawl 174 in a manner hereinafter appearing to disengage the stud 146 permitting the bail 140 to move back to its initial position under the influence of spring 143. The spring 177 keeps the pawl against pin 177a of member 170. At the upper end of the retraction of the operating lever, finger 193 of member 192 engages arm 182 of the locking pawl 181, to swing said locking pawl in a clockwise direction disengaging arm 167. The pull of the springs 124 will cause the bell cranks 120 to swing in a counterclockwise direction to again engage the rollers 122a with the setting wheels, and at the same time will press arm 137 in a counterclockwise direction causing the bell crank 166 to swing in a clockwise direction to thereby raise the link 170 for lifting said pawl 174 as heretofore described. Pin 188 limits the swinging movement of bell crank 166. If it is desired to inhibit restoration of all of the setting wheels, then finger 213 i swung upwardly to rotate pawl 202 so that as the operating lever is swung down, pin 163 will merely move through the slot 169 Without rotating arm 162,

When the pawl 202 is swung down by actuating lever 211, spring 164 will pull arm 162 against pin 180. The spring 164 is tensioned when arm 162 is rotated in a counterclockwise direction.

The machine is provided with a tabulating card holder and punch die assembly for punching the card in accordance with the settings of the setting wheels. The tabulating card C is partially shown in FIG. 2. This card may have a number of columns, as for example 90 columns. Each column may be divided into 12 vertically aligned sections. In a 12 wheel machine the die will have means to punch simultaneously one punch in each of 12 consecutive columns and the punch may be in one of 12 positions in each column. There may be successively from top down, 12, ll, 0, l, 2, 3, 4, 5, 6, 7, 8, 9, as indicated on the card shown in the drawing. The machine is further provided with means to move the card sideways so as to punch in any selected 12 columns. The mechanism for accomplishing this will be explained hereinafter. Thus in the card shown in FIG. 2, for purpose of illustration, there are punch holes P in 12 columns numbered to 16 inclusively. The punch holes are in 10 pro-selected positions in accordance with the setting of the setting buttons 89.

The card holder and punch die mechanism will now be described. This mechanism or assembly 240 comprises vertical plate 241 having a stem portion 242 and a top cross head portion 243. The cross head portion 243 is formed at the ends thereof with horizontal, outwardly opening notches 244 slidably engaging the upper horizontal guide pins 56. The plate 241 has at the bottom thereof a leg 245. Mounted on the cross head 241 is a spacer frame 247 having a top wall 248 and side walls 249, the lower ends of which are received in notches 250 in the top surface of the cross head. Attached to the rear of plate 241 are a pair of similar, registering die plates 251. The plates 251 have lower portions 252 riveted to plate 241 by four corner rivets 253. The upper portions 258 of the plates 251 engage the side edges of the frame or spacer 247 and are formed with 12 columns of rectangular punch die openings or slots 259 of a size to produce the punch holes P on the tabulator card C. In each of the 12 columns there are 12 vertically aligned slots or punch die openings, equally spaced apart, the spacing being similar to the spacing of 12 punch positions in each column of the card C. Thus, there are 144 punch holes or die openings 259 in each of the plates 251.

Contacting the rear of the rearmost plate 251 is a vertical thin spacer plate 260 likewise riveted to the die assembly by the rivets 253 passing through suitable openings in said spacer plate. Said spacer plate 260 has a horizontal upper edge 261 spaced below the lowermost punch holes 259 and somewhat below the upper edge of the cross head 243. The level of the edge 261 is such as to locate the lower edge of the tabulating card mounted thereon so that the punch holes will be properly located when the card is punched. The plate 260 has at its upper end side extensions or wings 262 extending to both sides of the spacing frame 247. The card C when placed in the machine rests on the upper edge 261 of the plate 260 and its wing extension.

Attached to the front of the wing extensions 262 are card guide plates 264 extending upwardly above said wings, and disposed on opposite sides of the spacer member 2'47. Attached to the rear of the wings 262 are upw-ardly extending card guide plates 265 extending upwardly therefrom and disposed on opposite sides of walls 254. Attached to the rear of plate 260 is another plate 251 aligned with the first mentioned plates 251 and likewise having slots 259, there being 12 rows of these slots, with 12 slots in each row, aligned with slots 259 in the first two plates 251. Between the two plates 251, on opposite sides of plate 260 and above the edge of plate 261 is formed a slot 266. The spaces between the guide plates 264 and 265 form extensions of the slot 266. The tabulating card is placed in said slot and the bottom edge of said card rests on the edge 261. Contacting the back of the last mentioned plate 251 is a thick plate 267 like- Wise riveted to all the plates 251 and 260 by said rivets 253. Said plate 267 is formed with 12 rows of slots 268 similar to and aligned with the slots 259 in the three plates 251. Extending rearwardly from plate 267 are parallel walls 270 lying inside of and adjacent to the wall 54 of bracket 50. The walls 270 are formed with upwardly and rearwardly inclined slots 271. The lower ends of the slots 271 register with the lower ends of the slots 55 in walls 54.

At the front of plate 241 is a fourth plate 251 similar to the other three such plates, and likewise assembled to plate 241 by means of said rivets 253. The upper portion of the last mentioned plate 251 contacts the front edges of the spacer frame 247. At the front of the last mentioned plate 251 is a plate 275 thicker than the plates 251 and attached to the assembly by said rivets 253. The plate 275 may be formed adjacent its lower end with a central opening 275a to reduce weight. At its upper 1 1 end, plate 275 is formed with a rectangular cutout forming parallel side portions 276 disposed on opposite sides of the group of punch slots in the plates 251. Fixed to said side portions 276 of plate 275 are guide pins 277 projecting forwardly thereof. Fixed to the plate 275 and located in the front of the side portions 276 thereof, is a retractor plate 280. Said retractor may be attached to said side portions 276 by screws or in any other suitable manner, and is formed with suitable openings through which the guide pins 277 project forwardly of the front face of said retractor plate. It will now be understood that punch die assembly 240 as a whole is supported on the upper guide pins 56 and may be slidably moved forwardly and rearwardly, the attached assembly being held together by the rivets 253 and by the attaching means which attach the retractor plate 280 to plate 275.

The retractor plate 280 is formed with 12 horizontally transverse slots 282. The height of the slots 282 is equal to the height of the slots 259. However, the lower edges of the slots 282 are below the lower edges of the corresponding row of slots 259, and the upper edges of slots 282 are below the upper ends of the slots 259 in the corresponding row of slots. In other words, the 12 slots 282 are offset downwardly from the 12 slots 259 in the plates 251.

Attached to the rear face of plate 260 is a plate 280a similar to plate 280 and aligned therewith and having rows of slots 282a aligned with the rows of slots 282 in plate 280. Plate 280a and plate 60 are formed with suitable openings to receive the guide pins 277, and attached to plate 60 are guide pins 285 passing through suitable openings in plate 280a and in the plates 280 and in portions 276 of plate 275. to insure perfect alignment of movement of the die assembly 240 relative to plate 60.

Slidably mounted on the openings 259 of plates 251, and in the slots 282, 282a of plates 280, 28011, are punch die elements 290. There are 12 columns of punch elements 290, with 12 elements in each column, making it a total of 144 punch elements. The punch elements are horizontal and extend from front to rear. They are of rectangular transverse cross-section. Their front edges are sloped downwardly and rearwardly as at 291. Normally, when the machine is at rest, the front ends of the punch die elements are located adjacent the slot 266 which receives the tabulating card. Adjacent their rear ends the punch elements 259 are formed in their upper edges with notches 292. The plates 280 and 280a are normally located at the ends of the notches 292. The lower edges of the transverse portions 293 of plate 280 between the slots 282 and the lower edges of the transverse portions 294 of the plate 280a between the slots 282a, contact the lower edges of the notches 292.

Slidably mounted in each of the slots 38 of plate 37 is an interposer 300. There are 12 interposers for the 12 setting wheel machine. Each interposer has a vertical rack portion 301 slidable in the slot 38 and held in the slot by one of the front plates 40. The rack portions 301 have front rack teeth 302 meshing with the pinions 128. There are 12 pinions which mesh with the gear teeth 81 of the 12 setting wheels 77 and with the rack teeth of the 12 interposers 300. The interposers 300 further comprise thin front upwardly extending arms 304 sliding in the respective slots 67 of the plate 63. When the machine is at rest the racks301 are in their up positions with the upper ends of the racks contacting plate 64, and with the upper ends of the arms 304 contacting said plate. The lower ends of the interposers are located just below the pinions 128. At the upper end of each arm 304 is a forwardly extending head 305. It will be noted that the heads 305 are aligned with the 12 vertical columns of punch element 290 and are spaced close together, whereas the rack portions 301 are spaced far apart. The lower ends of the arms 304 are connected to their respective rack portions by means of rearwardly extending portions 306,

Thus, guide pins 277, 285, serve from which extend outward portions 307, from which extend again rearward portions 308 (see FIG. 9). Thus the interposers are all the same except that the lengths of the portions of 306, 307 and 308 vary, as shown in FIG. 9. The 6 interposers on one side of the machine are sym metrically disposed with respect to the interposers on the opposite side of the machine. It will now be understood that as any setting wheel is rotated, its associated interposer is slidably moved to bring its heads 305 to one of 12 vertical positions. Thus, if a button 89 is moved to 3 position, its corresponding interposer will be moved down to bring its head 305 down to a position where it is located directly in back of position 3 in the associated column of the die.

It will now be understood that when the setting wheels are set, the interposers are correspondingly set behind the punches which are to punch the desired punch holes in the card. Means is provided for moving the die punch assembly together with the card forwardly to elfect a punching operation. It will be observed that the shaft 74 extends across the machine and passes through suitable bearings in the walls 54. At one end, the said shaft 74 projects beyond side plate 32 and attached to the extending portion is an arm 310 carrying at its outer end a pivot pin 311 carrying a roller 311a. Fixed on said shaft 74 is a collar 313 (FIG. 11) connected by coil spring 314'to a fixed post 315 on the back wall 51. The spring 314 tends to rotate the shaft 74 in a clockwise direction, looking at FIG. 11 of the drawing. Rotatably mounted on shaft 71 and between the side plate 32 and the sleeve 151 of the operating lever is a star wheel 320 having four equiangularly spaced cammed arms 321 extending from a central sleeve. The roller 311a on arm 310 fits into the notches between said arms. On the star wheel are four equi-angularly arranged cammed ratchet teeth 322. Slidable in the sleeve 151 of the operating lever are a pair of diametrically opposed spring pressed pins 324 held in abutting relation with the teeth 322. As the operating lever 150 is pulled down, the pins 324 engaging the abutment ends of a pair of diametrically opposed ratchet teeth 322, will move the star wheel in a counterclockwise direction, looking at FIG. 4, through an angle of 90. During this operation, arm 310 will be moved in a counterclockwise direction until the roller 311a passes the high part of the cammed arm 321 which engages the roller. The spring 314 will then move the arm 310 in a clockwise direction as the oammed arm passes said roller 311a and the roller then moves into the next notch between the cammed arms. Thus, each time the operating lever makes a full 90 down stroke, arm 310 and hence shaft 74 is oscillated. On the up-stroke of the operating lever the pins 324 are pushed outwardly against their spring by the cammed portions of the ratchet teeth 322, so that the star wheel only moves in one direction, and only during the downstroke of the operating lever.

Attached to shaft 74 and located centrally of the machine in front of the cut-out 52 of the backwall 51 is a yoke 330 (see (FIGS. 5 and 8). The yoke 330 has apertured ears 331 supporting a transverse horizontal shaft 332. Attached to shaft 332 is a channel member 333 having an upwardly and forwardly inclined back wall 334 and parallel side flanges 335 having apertures at their lower ends receiving the outer ends of shaft 332. Supported by the upper ends of the side walls or flanges 335, is a transverse horizontal shaft 336 the outer ends of which pass through the upper vertical slots 55 and the upper inclined slots 271. On said shaft 336 are rollers 336a engaging within said slots. Normally, when the operating lever is in its up position, the shaft 336 will be at the lower meeting ends of the slots 55, 271. It will be noted that the flanges 335 of member 333 are disposed parallel to and in inwardly spaced relation to side walls 270. Between the flanges 335 and the side walls or flanges 270 are vertical side plates 340 formed at their upper ends with openings through which the transverse shaft 336 passes. On the lower ends of plate 340 are stud shafts or rollers 341 passing through the openings 55 and 271 at the lower ends of the walls 54 and 270. It will now be understood that as the operating handle is swung downwardly, shaft 332 will be swung upwardly and forwardly to move the shaft 336 upwardly for causing the entire die assembly 240 to move forwardly. During such action the punches 290 which have interposers backing them up will punch through a card in slot 266. In FIG. is illustrated the punching position of the die after it has been moved forwardly. During the punching action, the plate 280 will move toward plate 280a. When the operating lever is released and swings upwardly, yoke 330 will be swung down or in a clockwise direction, looking at FIG. 5, pulling the rollers 336a downwardly to again move the punch and die assembly rearwardly. During the forward stroke of the die assembly, the punches which are backed up by interposers punch through the card. However, the remaining punches are pushed back by card C. During the rearward movement of the punch die assembly 240, the plate 280 will move all the punches which have been moved forward by the card, in a rearward direction toward their initial positions. This is due to the engagement of plate 280 with the forward end of the notches 292.

Means is provided for moving the card on the die assembly. To this end there is rotatably mounted on said shaft 42, and to the left side of side plate 31, as shown in FIG. 6 of the drawing, a sleeve 350 projecting through the adjacent side wall of the casing. Mounted on the sleeve 350 for rotation therewith, is an index wheel 351 to which is attached a hand wheel or knob 352. The wheel 351 has a rim flange 353 which is divided into angular subdivisions 354 corresponding to the angular subdivisions on the portions 28a of the bezel. For an 80 column tabulating card there are 80 subdivisions 354 numbered from 1 to 80, successively, as shown in FIG. 1 of the drawing. Mounted on the adjacent side wall of the casing and between the casing and wheel 351 is a segmental index or indicator bracket 355 which is also divided into 12 angular subdivisions corresponding to the subdivisions on portions 28a of the bezel, and to the subdivisions 354 of wheel 351. However, the 12 of the subdivisions 355 on the index are marked with numbers from 1 to 12. Upon turning the wheels 352, wheel 351 will be rotated to align the 12 subdivisions 355 with any selected 12 successive subdivisions 354. Means is provided to bring selected 12 consecutive columns of a card C mounted on the punch and die assembly, into registry with the 12 punch columns of the assembly. To this end there is mounted on sleeve 350 a bevel gear 360 (see FIGS. 3 and 6). Mounted on side plate 31 is block 361, carrying a bearing 362 through which passes a downwardly and rearwardly inclined shaft 363. At the forward end of this shaft is a ibevel gear 364 meshing with gear 360.

Fixed to the rear of bracket 50 is a plate 370 attached to the bracket by screws 371. Said plate 370 has a fiat portion 372 contacting the back of wall 51. Extending upwardly and inclined rearwardly from portion 372 is a portion 373 provided with an extension 374 carrying a bearing 374a in which is journaled the rear end of shaft 363. It will be noted that the portion of member 370 above portion 372 inclines away from wall 51. Said member 37 0 has a portion 375 which traverses the cutout 52 and terminates in an offset finger 376 contacting the back of plate 51, and attached thereto. Fixed to portion 375 of member 370, as by screws 377, is an upwardly extending apron 378. Fixed to the back of plate or wall 51 of bracket 50, as by screws 379, is a lower horizontal rail member 380 formed in its upper edge with a V-shaped groove 381. Also attached to the rear of said wall 51 is an upper rail member 382 spaced from and aligned with the lower rail member 380 and fixed to said wall 51 by screws 383. Rail 382 is symmetrical to rail 380 and has in its lower edge a V-shaped groove 384. Mounted for sliding movement on and between the rails 380, 382 is a card carriage member 385. Said carriage member 385 comprises a plate 386 which is in a vertical plane but extends horizontally. Plate 386 is formed with a V- shaped groove 387 in its upper edge and with a V-shaped Between the grooves 384,

groove 388 in its lower edge. and 387 are balls 389. Between the grooves 388 and 381 are balls 390. Thus, the plate 386 has ball bearing movement on the upper and lower rail members. Plates 392 fixed to the ends of the lower rail members 380 project upwardly overlapping the ends of the groove 381 and plates 393 fixed to the ends of the upper rail member 382 projects down to overlap the groove 384. Brackets 395 attached to plate 386 have fingers overlapping the ends of grooves 387 and 388, thus preventing the balls 389 and 390 from coming out from between the plate 386 and the upper and lower rail members.

Fixed to the ends of plate 386 are brackets 400 having forwardly extending arms 401. Mounted on the forward ends of arms 401 are vertical pins 402 located in the plane of slot 266 which receives the tabulating card. The arms 400 are at a level below the upper end of the punch and die assembly and above the card guides 264 and 265.

Rotatably mounted on said vertical pins 402 are card guides 403. Said card guides are substantially similar and symmetrically disposed. Each card guide comprises a channel shaped member 404 provided with a vertical through-opening 405 to rotatably receive the pin 402. Torsion springs 402a or pins 402 may be provided to rotate members 404 inwardly and rearwardly. Extending from the lower end of the channel shaped member 404- is a stop arm 407 adapted to contact arm 4,01 under influence of opening 402a to limit the rotation of member 403 to positions where said members are in alignment. Each channel shaped member 403 is formed with a channel 407 in which is slidably mounted an arm 408 attached to the channel shaped bracket in horizontally adjusted position by screws 409. At the inner end of arm 408 is a vertical arm 41!) extending upwardly and downwardly therefrom and formed to its inner side with a vertical groove 411. The grooves 411 are in the plane of card slots 266. Extending from the upper ends of the arms 410 are inwardly extending wings 412 disposed at the back of the slots 411. Also extending from arms 410 adjacent the upper ends thereof are wings 412 each having a triangular portion 413 projecting forwardly with an upwardly and forwardly inclined flange 414. Thus, when a card is inserted in the carriage, the lower end of the card may engage in front of the wings 412 and in back of the inclined flange 414 so as to be guided to slots 414.

Attached to the rear of plate 386 are spacers 428 to which is attached a plate 421. The lower end 422 of the plate 421 is inclined downwardly and forwardly and is formed at its underside With rack gear teeth 423. Journaled in portion 375 of plate 370 and disposed in front of said portion is a pinion 425 meshing with the rack gear teeth 423. Journaled on plate 370, as at 426, is a pinion 427 meshing with pinion 425. Also journaled on plate 378, as at 428, is a pinion 429 meshing with pinion 427. Mounted on the rear end of the shaft 363 in front of extension 374 of plate 370, is a pinion 430 meshing with pinion 429. It will be understood that when wheel 352 is rotated, shaft 363 will rotate the pinions 430, 429, 427 and 425 for moving the entire card carriage in one direction or the other, depending upon the direction of the rotation of the wheel. As the card carriage moves to the right or left, the card on the punch and die assembly will be moved to the right or left to bring the desired 12 columns of the card directly in back of the 12 columns of the punch die. As the operating lever is moved downwardly and the punch and die assembly 240 is moved forwardly, the portion of the tabulating card in back of the die assembly will be pressed forwardly, thereby causing the ends of the card engaging in the grooves 411, to swing the inner ends of the 15 card guides 403 forwardly on the pivot pins 402. Within the groove 411 of the card guide 403 at the left side of the machine, is a small leaf spring 415 to engage one end edge of card C, for resiliently pressing the card against a positive stop of the other card guide 403, to insure proper alignment of the card in the machine.

Means is provided to retain the carriage in any position to which it is moved by turning the selector wheel or knob 352. To this end there is pivoted to back wall 51, as by pin 450, an arm 451 carrying a roller 451a pressed down against teeth 452 formed in the upper edge of plate 421 by a spring 453. Roller 451a clicks over the teeth 452 which correspond to the teeth 423 at the lower end of said plate 421.

Mounted on bracket 50, between side walls 54 thereof, and adjacent the upper end thereof, is a transverse horizontal shaft 460. Rotatably mounted thereon is a lever 461 having a forwardly and downwardly extending arm 462 engaging beneath shaft 336. Lever 461 has a rearwardly projecting arm 464 having a knife edge 465 at its underside. A coil torsion spring 466 on shaft 460 tends to rotate lever 461 in a clockwise direction, looking at FIG. to move knife edge 465 down. Shaft 336 normally keeps edge 465 raised. When the operating lever is pulled down, shaft 336 moves up to allow knife edge 465 to engage between a pair of teeth 452, to lock the carriage during the punching operation.

It will thus be seen that there is provided an apparatus in which the several objects of this invention are achieved and which is Well adapted to meet the conditions of practical use.
